EPSG:32633 — WGS 84 / UTM zone 33N

Source: EPSG Dataset via PROJ 9.5.1 · Updated 2026-10-05

Summary

EPSG:32633 (WGS 84 / UTM zone 33N) is a projected coordinate reference system on the World Geodetic System 1984 ensemble datum using the Transverse Mercator method, with coordinates in metres. Area of use: Between 12°E and 18°E, northern hemisphere between equator and 84°N, onshore and offshore. The datum is an ensemble with about 2.0 m accuracy, so precise work should name a specific realization.

Type: projected
Datum: World Geodetic System 1984 ensemble
Units: metre

Example coordinates

A WGS 84 point at longitude 16.5°, latitude 24.0° (inside the area of use) has these coordinates in EPSG:32633:

Computed with PROJ using the EPSG default operation: axis order change (2D) + UTM zone 33N.
Axis	Value	Unit
E	652,578.355	m
N	2,655,039.017	m

At this point the projection scale factor is 0.99988755 and the grid convergence is +0.610223°.

PROJ string

A PROJ string cannot carry every EPSG detail (axis order, datum ensemble, transformations). Prefer WKT2 or the EPSG code itself.

Proj4js definition used by the converter

+proj=utm +zone=33 +datum=WGS84 +units=m +no_defs

No datum shift is needed: this CRS is on WGS 84 or a datum Proj4js treats as equivalent at the metre level.
